Comparative study of 99mTc-ECD and 99mTc-HMPAO for peri-ictal SPECT: qualitative and quantitative analysis.
OBJECTIVES Most studies that clinically validated peri-ictal SPECT in intractable partial epilepsy had used technetium-99m-hexamethylpropylene amine oxime (99mTc-HMPAO or 99mTc-exametazime) as the radiopharmaceutical. Because of some theoretical advantages, technetium-99m-ethyl cysteinate diethylester (99mTc-ECD or 99mTc-bicisate) is increasingly being used instead. This study compares unstabil...
متن کاملDynamic and static 99mTc-ECD SPECT imaging of subacute cerebral infarction: comparison with 133Xe SPECT.
UNLABELLED 99mTc-ethylcysteinate dimer (99mTc-ECD) SPECT imaging reportedly fails to show reflow hyperemia in patients with subacute stroke. This study attempts to determine the clinical usefulness of dynamic 99mTc-ECD SPECT in evaluating regional blood flow in subacute cerebral infarction and the kinetic behavior of 99mTc-ECD in infarct areas. METHODS 133Xe and consecutive dynamic and static...
متن کاملPET physiological measurements using constant infusion.
A wide range of study designs can be used with positron emission tomography methods to provide quantitative measurements of physiological parameters. While bolus injection of tracer is the conventional approach, use of combined bolus plus constant infusion provides a number of advantages for receptor-binding tracers. Of recent interest is the use of this approach to dynamically follow the displ...
متن کاملNeuroGam Software Analysis in Epilepsy Diagnosis Using 99mTc-ECD Brain Perfusion SPECT Imaging
BACKGROUND The aim of this study was to explore the value of NeuroGam software in diagnosis of epilepsy by 99Tcm-ethyl cysteinate dimer (ECD) brain imaging. MATERIAL AND METHODS NeuroGam was used to analyze 52 cases of clinically proven epilepsy by 99Tcm-ECD brain imaging. The results were compared with EEG and MRI, and the positive rates and localization to epileptic foci were analyzed. RESULT...
متن کاملHeparin administration by constant infusion pump.
It has been claimed that a raised blood lead level is a common finding among mentally retarded children and that this is of aetiological significance. One hundred and twenty-three mentally handicapped children of uncertain aetiology, 24 with mongolism, and 73 controls have been examined for lead intoxication. The results indicate that the three groups do not differ significantly as regards bloo...
